13 Claims.

, 1 r This invention relates generally to air conditioning apparatus and more particularly to a wall-mounted console type air conditioner.

The console type air conditioner has not become as popular as the window-mounted air conditioner in recent years largely because it obstructs floor space and'is more costly to manufacture. The window-mounted air conditioner has the disadvantage of obstructing a large portion of a Window and preventing closure of the Window. The present invention is concerned with providing an air conditioning unit which will overcome these disadvantages.

One object of the present invention is to provide a console type air conditioner which is adapted to be mounted on the wall of a room below an outside window, thus eliminating the costly provisions of mating the floor to sill height of the room, for instance, with an air conditioning unit that rests on the floor.

Another object of the invention is to provide means for attaching the air conditioner to the Window sill of the window. A j Another object of 'the invention is to provide means for adjusting the cabinet of the air conditioner so that it will extend parallel to the inside surface of the wall.

Another. object of the vinventionis to provide a console model air conditioner whichis spaced entirely above a floor of a room so that the floor beneath the conditioner can be easily cleaned.

window into the high side compartment of the Another object of the invenair conditioner. tion is to provide an air'duct which will prevent the cabinet of the air conditioner. a

Another object of the invention is to provide .an air duct'which will permit complete closing of the window. I 7 Another object of the invention is to provide a console model air conditioner that will obstruct a minimum amount of fioor space.

Another object of the invention is to provide parent fromthe following description and drawings in which like reference characters denote like parts throughout the several views. It is to be expressly understood, however, that the drawings are for the purpose of illustration only and not adefinition of the limits of the invention, reference being made for this purpose to the appended claims.

The high sid compartment 16 is separated into an inlet chamber 9| and an voutletclaarnber 82 by adividing wall 183. A condenser 84 extends across the h he hg i qh h i eshhmh 11 and s shhre t s upp rt mhhh fl w i h a w turried edge portions 85 and 8]. The support member 85 extendsacross the width of the cas-- ing .26 with the edge portions 85 and 3'! being secured to the frame members 2! and 22. The downturnededge portion 8] extends into contact with the overturned edge portion of the rear wall 28 of the casing 25' whereby it will prevent rain from entering said casing.

A filter element ,98 is removably secured between the inlet 95 and evaporator 95. A centrifugal type fan 99 is installed above the evapo h'th and is h h idesi wit eh inl t lflfih ou let lpl. The top cover is provided with a louvered opening 192 which fits over the outlet [9| of the fan' 99. electric motor 193 for driving t fan .9 sss hred w th e h h sid compartment 16 and is provided with an armat r shaft 4 wh ch est-end through the tieh W l 1-8 a vhihh hlh t th fa 98 damper I95 is slidably secured to the ,top cover 32 and is adapted to be moved away from openi s'l t th 0.1 9 5 hqsit hn shown by solid lines in Fig. l, or to be moved to a closed position shown by dotted lines where it covers and closes the opening M2. "The front edge of the damper N15 is provided with a downturned flange which fits within a slot i131 provided in the parhh .1 h th damp '95. i in h position- The refrigeration system is charged with a suitable refrigerant which is compressed by the motor-compressor unit 9| and then forwarded by a conduit N16 to the condenser 84. After flowing through the condenser 84, the refrigerant is then metered into the evaporator 95 by a small diamesagas compressorunitfll." I c V v The unit It can be easily and quickly assembled to the Window sill l6 and brought into plumb position. Controls may be provided for automatically controlling the operation: of the refrigeration system but are not shown since they are not important to the invention. With the motor-compressor unit SIL and electric motor 89 operating, outside air will be pulled through the ducts Eil, 68, and 49 into. inlet chamber 3| by fan 98, over one en'dof co'ndenser ttl, then forced through opening 38, v upwardly through outlet chamber 82, over the opposite "end of con denser 84 and then dischargedthrough the ducts 49, 68, and 6!. The outside airhas a path of low resistance through the high side compartment "it whereby the condenser 84 will be adequately cooled. The motor-compressor unit 9i and electric motor 89 will also be cooledby the outside air.

During operation of the refrigeration unit, room air is pulled through grille 9'! by blower 99 and circulated through filter 93: and over the evaporator 95, after which it is pulled through blower inlet I06 and then discharged into the room through the louvered'opening I02. The room air will be thoroughly cleaned by the filter element 98 and then cooled to a desired temperature by the evaporator 95.

To add fresh outside air to the room, door 93 is opened to the position shown by solid lines in Fig. 1 so that a portion of the air being circulated through outlet chamber 82 will be forced into the room. This air is filtered by filter element 94, then directed upwardly by door 93 toward grille 91 where it will be' picked up by the air stream entering low side compartment 15 and filtered a second time by filter element 98 before finally being cooled by evaprator !l5. If it is desired to evacuate air from the room, fan motor I63 may be operated independently. Damper IE is moved to closed position, as in dicated by dotted lines in Fig, 1, whereby the air pulled through grilles! by fan 59 'will be forced through the slot It! in the partition wall Hand forced outside through outlet chamber 82 and ducts 49, 68, and SI. .7 From the foregoing it can be seen that an air conditioning unit It} is provided which is mount ed to a window sill IS with the floor l2 below the unit being left unobstructed so that it can be easily cleaned, The entire weight of the unit lil is carried by the outer wall H of the room so that no damage will be done to the fioor. it due to the weight of the unit. The ducts '61, 68 and d9 provide a free path for outside'air and prevent the entrance of rain into the casing 26. Window sash 38 may be lowered without the removal of. any parts. By properly adjusting the door 93 and damper M35, the room air may be conditioned inany desiredmanner. 4 ,3 While the invention has been shown in a preferred form, it will be obvious to those skilled in the art that it is not so limited but is susceptible to variou changes and modifications Without departing from the spirit thereoii l \What is claimedisi 1.
